PWYW release for a major musical act, and created awareness of PWYW models. In December 2007, punk/metal record label Moshpit Tragedy Records became the first to operate fully under the PWYW download system. In 2008, Wheatus moved to a PWYW system for all their future and past albums they held the rights to. Koo Koo Kanga Roo, a comedy kids/hip hop duo, released all of their recorded music under a PWYW system. The group has referred to themselves strictly as a live band, and thus give away their music solely so as many people as possible can hear it and be able to sing and dance along with it at their performances.

In late 2012, McPixel had a PWYW weekend, in partnership with The Pirate Bay, as the creator Mikolaj Kaminski wanted people to try his game to encourage them to buy it. Canonical implemented this system on the Ubuntu download page. Their message varies, but usually asks to "Show Ubuntu some love. Or, alternatively, help out in the bug tracker ;)". One can adjust the sum they wish to contribute for each development initiative from $0 to $125. Alternatively, there is an option to skip the payment and go straight to download of selected OS type.
